Installation Insights

Securing an efficient and properly installed boiler is critical for any household's water heating needs. This section provides a detailed look at the steps involved in the installation process, factors influencing costs, and the importance of hiring a certified professional.

Boiler Installation Process

When installing a new Alpha boiler, the initial step involves removing the old unit, if applicable. The appointed heating engineer then conducts a thorough assessment of the site to align with safety protocols and fit the new boiler correctly. These processes include checking for adequate ventilation, connecting the boiler to water pipes, and establishing electrical connections for the unit's control systems. Throughout the installation, adherence to the manufacturer's guidelines and UK building regulations is mandatory.

Determining Installation Costs

The installation costs for an Alpha boiler can fluctuate widely based on several elements. The type of boiler and the complexity of the installation play significant roles; installing a combi boiler may differ in price compared to a system or heat-only boiler. An online quote can provide a preliminary figure, yet a specific estimate requires a professional's assessment. In general, new boiler costs, minus installation fees, range from £625 to £1,925.

Choosing a Certified Engineer

Opting for a Gas Safe registered engineer is not only a recommendation but a legal requirement for any gas boiler installation in the UK. Verifying the credentials of the engineer ensures that they have the necessary competency for safe and effective installation.

iHeat New Boiler Costs

Boilers can be a daunting purchase for many people as they’re an appliance with a lot of responsibility, providing heat for you and your family is something you want to get right. Boilers aren’t exactly a quickly disposable item either, potentially lasting you a decade.

Effectively, new boiler cost can be split into two segments: the first is the actual boiler itself (unit price), and the second is the cost of the boiler being installed (set up) in your property by an expert engineer. 

Here at iHeat, we want to remove all of this undue stress and make the decision making process of upgrading to a new central heating system, as easy as possible.

Boiler costs can vary depending on a number of factors including their brand, model, fuel, output, warranty, labour and installation type. Typically a new boiler will cost between £1,845 and £3,500, below is a list of average boiler installations offered by iHeat (guide only).
